Melbourne, Dec 4 : Britney Spears almost flashed her boobs when she stepped out in a cleavage-busting dress for her 27th birthday celebrations in New York.

The star, who made her British TV comeback performing new single Womanizer on the X Factor at the weekend, wore a dress with a neckline so low, she had to struggle to stop anything popping out, reports the Courier Mail.

She was photographed wearing the little black dress to the Tenjune nighclub.

Meanwhile, the pop star has confessed that she loves her toned body but hates the tough work out session.

The ‘Hit Me Baby One More Time’ hitmaker, who gained pounds after giving birth to her kids Sean Preston, three, Jayden James, two, has revealed that it took a lot of effort to get back into shape. (ANI)
